Compressive wedge cleaving of optical fibers

摘要

Lengths of an optical fiber may be broken apart from one another while a cross-sectional region of the optical fiber is in a state of multi-axial compressive stress, and the multi-axial compressive stress extends across the optical fiber. The breaking can include propagating a crack across the optical fiber. The crack can be positioned in sufficiently close proximity to the cross-sectional region so that the multi-axial compressive stress restricts the crack from penetrating the cross-sectional region. At least a portion of the optical fiber may be in tension during the breaking.

1. A method for at least separating lengths of an optical fiber from one another, comprising:
breaking the lengths of the optical fiber apart from one another while
a cross-sectional region of the optical fiber is in a state of multi-axial compressive stress, andthe multi-axial compressive stress of the cross-sectional region extends across the optical fiber; wherein the breaking is comprised of
propagating at least one crack across the optical fiber while the cross-sectional region is in the state of multi-axial compressive stress, andthe at least one crack being positioned in sufficiently close proximity to the cross-sectional region while the cross-sectional region is in the state of multi-axial compressive stress so that the multi-axial compressive stress in the cross-sectional region restricts the at least one crack from penetrating the cross-sectional region.
